6. (4 pts) This question is not part of the three mandatory questions that you must solve. This is only for bonus. 2x = 2 x = 1 Consider the two systems of linear equations: 4y = 0 and x + y = 3 y = 0 x + y = 3 Answer the following question without solving the least-squares problems (i.e., by simply under- standing least-squares solutions): Do the two systems above have the same least-squares solution? Justify your answer. 6. (4 pts) This question is not part of the three mandatory questions that you must solve.
